DROP CAST()                      SQL Commands                      DROP CAST()

NAME

       DROP CAST - remove a cast

SYNOPSIS

       DROP CAST (sourcetype AS targettype) [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP CAST removes a previously defined cast.

       To  be  able to drop a cast, you must own the source or the target data
       type. These are the same privileges that are required to create a cast.

PARAMETERS

       sourcetype
              The name of the source data type of the cast.

       targettype
              The name of the target data type of the cast.

       CASCADE

       RESTRICT
              These  key  words  do  not  have  any effect, since there are no
              dependencies on casts.

EXAMPLES

       To drop the cast from type text to type int:

       DROP CAST (text AS int);

COMPATIBILITY

       The DROP CAST command conforms to the SQL standard.
